We already know that sleep deprivation can negatively affect your energy levels, concentration, and moods. But it can also affect your skin—both in ways you can see and ways that you can’t.
“Sleep is one of the most important things you can do for your skin,” dermatologist Dr. Dennis Gross told The Telegraph. “During the day, your skin is in a protective state, warding off elements such as sun damage or oxidation, whereas at night, your skin goes into repair mode, regenerating new skin cells and cycling oxygen and nutrients,” says Gross.
Some of the most obvious signs of bad sleep are dark circles under your eyes or puffy eyes. “For the most part, dark under-eye circles are the result of lifestyle habits such as smoking, overindulging in alcohol, and not sleeping enough,” Gross said. Read on to learn more about how sleep deprivation impacts your skin.

Sleep And Skin Health
One study from 2015 evaluated the sleep quality of 60 women aged 30 to 49. Those in the group who were poor sleepers (meaning they got less than five hours of poor-quality sleep for at least one month before the start of the study) showed more clear signs of “intrinsic aging”. These signs were all visible to the human eye and included uneven skin tone, fine lines on their skin, and less elasticity in their skin.
The researchers also tested participants’ skin to see how quickly their skin barrier repaired itself and how long it took their skin to recover from UV erythema (aka sunburn). They found that poor sleepers’ skin repaired itself more slowly and recovered from sunburn more slowly.
“Sleep deprived women show signs of premature skin aging and a decrease in their skin’s ability to recover after sun exposure,” researcher Dr. Elma Baron concluded.
There are other ways sleep deprivation can affect your skin. Dermatologists Dr. Lily Talakoub and Dr. Naissan Wesley wrote in an article for Dermatology News, “Sleep deprivation affects wound healing, collagen growth, skin hydration, and skin texture. Inflammation is also higher in sleep-deprived patients, causing outbreaks of acne, eczema, psoriasis, and skin allergies.”
According to Talakoub and Wesley, there are treatments that can help resolve some of these issues. But, they concluded, “beauty sleep is both necessary and irreplaceable” to keep your skin as healthy as possible.
